optimum infeed location for Tarm

[penfrydd]

Okay...so I'm putting the circ on the return, as noted in Tarm drawings, with expansion tank and spirovent on supply side of circ. Where is the best place to put the cold water infeed with autofill? Common sense tells me it should be on the supply side of the spirovent; correct?

The answer to this should get me in position to finish all the plumbing...we'll see. Thanks for all the helpful advice.

You want the spirovent etc on boiler out pipe / system supply / that way you will get any trapped air from boiler before it gets to system zones also it's the hottest water and allows for removal of air from boiler.
I just put this on other thread....

On Boiler Room Home page there is a "sticky note" Simplest Pressurized storage. This is the order of things. In the diagram at the top left where the expansion tank is that is where you want the spirovent with tank hanging off bottom tap. Put the relief valve on the boiler itself.
